FMI Add-in for Excel

High-fidelity physical models are valuable tools for assessing system-level performance and robustness early in the product development process.

The FMI Add-in for Excel® links state-of-the-art Modelica-compliant tools, including Dymola, to Microsoft Excel® through the FMI standard. Inputs and parameters of models imported into Excel® are conveniently configured by standard spreadsheet operations.


  • Allows users to exploit state-of-the-art physical modeling tools within an easy-to-access Microsoft Excel® environment
  • Enables parameter sweeps and sensitivity analysis that can provide insights into the impact of component variation on system behavior early in the design cycle
  • Provides simulation results within standard Excel spreadsheets, enabling organizations to quickly and easily exchange information among all shareholders in the enterprise
  • Maintains flexibility and consistency through the FMI standard.

Key Features

  • Import and simulation of Functional Mock-up Units (FMUs) in Microsoft Excel®
  • Parameter sweeps and sensitivity analysis
  • Parallel computations on multi-core platforms
  • Batch simulation and design space exploration
  • Supports FMI for Model Exchange 1.0 (initialization of models)
  • Supports FMI for Co-Simulation 1.0 (initialization and dynamic simulation)

The FMI Add-in for Excel enables steady-state and dynamic simulation of physical models integrated in a spreadsheet environment. Batch simulations and parameter sweeps are accessible through easy-to-use functions that enable users to quickly get up to speed with sophisticated model analyses.
